Summary:PURPOSE: To surly mount/demount a delivery port of a submerged pump made surly sealable also when driven relating to an introducing port of a connecting pipe set up in a manhole. CONSTITUTION: When a groove part 35b provided in a mounting/demounting part 35 of a submerged pump is fitted to a guide rib 42 of a connecting pipe 41 arranged in a manhole, a machine screw 35c provided in an outer side inner side surface in the groove part 35b is brought into press contact with a side surface of the guide rib 42. Since the machine screw 35c is positioned in a distant side from the center of gravity of the submerged pump, large moment by dead weight of the submerged pump acts in the machine screw 35c, to bring a delivery port 32 of the submerged pump into pressure contact with an introducing port 41b of the connecting pipe 41. By driving the submerged pump, when a liquid is delivered from the delivery port 32, the submerged pump tends to float up by this delivery pressure, but by large moment due to the dead weight of the submerged pump, its floating up is prevented.
